Patent DE-3243640-A1 (DE)
Inventor: WOLF FRANZ-JOSEF
IPC: F16D3/50
Filed: 1982-11-25
Abstract: A rotationally elastic coupling with two half-couplings can be twisted relative to one another, these half-couplings being connected with one another so as to transmit forces by means of a sprung intermediate link and by means of a movement-converting intermediate link which converts a rotation into a translational movement or, vice versa, a translational movement into a rotation. At least one sheet metal support is provided which is in contact at a radially outward position with one of the sprung intermediate links which in turn is supported rotationally solidly and frictionally at a radially inward position with one of the two half-couplings. The sheet metal support is subjected to forces directly or by means of a coupling element of the movement converting intermediate link, in particular an eccentric or a crank, this movement converting intermediate link being rotationally and rotationally solidly connected to the other half-coupling. Using such a coupling, practically linear and soft spring characteristics can be produced for high torques over twist angle ranges of far beyond 30 DEG .

Title: Corner piece having a corner connector for connecting walls of a lighting fixture frame
Inventor: BRUEGGEMANN JUERGEN
IPC: F21S2/00
Filed: 1982-11-26
Abstract: If lighting fixtures are to be arranged in the form of continuous rows of luminaires and/or figures, for example having a star-shaped node, special connecting parts on which transverse walls are mounted are required for each configuration in order to connect the individual lighting fixtures. The invention largely reduces this complexity in the case of lighting fixtures having a lighting fixture frame whose longitudinal and transverse walls (1, 2) have the same profile and are plugged together via corner connectors (3). According to the invention, two corner connectors (3, 3', 3'') belonging to different lighting fixture frames form a common corner piece (30) connecting two lighting fixture frames to one another. <IMAGE>

Title: Method of automatically allocating and connecting two bodies, in particular a wheel rim and a wheel hub
Inventor: SCHUPP GERHARD
IPC: B60B31/00
Filed: 1982-12-14
Abstract: The invention relates to a method and a device for automatically connecting two bodies by means of bolts, rivets or the like. In the exemplary embodiment of the assembly of a wheel, the hole patterns of the wheel rim (20), wheel hub (25) and multiple screwdriver device (4) must be made to coincide. To this end, the fixed hole pattern of the hub is searched for by rotation of a prepositioned feeler head (2) with feeler members (3). This rotary movement is transmitted synchronously, but in the reverse direction of rotation, to the multiple screwdriver device (4) and a gripper device (5) via a gear unit (15). Both devices (4, 5) have taken hold of a wheel (19) with pre-aligned wheel rim (20) beforehand in such a way as to facilitate assembly and now rotate with the wheel (19). After the rotary movement is complete, the hole patterns of hub (25) or feeler head (2) and of the wheel rim as well as the multiple screwdriver device (4) coincide opposite one another in mirror image with regard to a pivot axis (12). The feeler head (2) and the multiple screwdriver device (4) are mounted in a common bearing arm (6) which rotates about its pivot axis (12) after the hole pattern of the hub is located and brings the wheel rim together with the multiple screwdriver device (4) into an assembly position opposite the wheel hub (25) in such a way that the hole patterns coincide. <IMAGE>
Patent DE-3246454-A1 (DE)
Inventor: KRUMMEL PETER
IPC: H02H9/04
Filed: 1982-12-15
Abstract: In an inverter controlled with a firing unit connected to switches and defining an operating frequency, a resonant frequency of a series oscillating circuit of the inverter connected to one of the switches is placed below this operating frequency. Given this operating situation, a short of the d.c. voltage source is impossible. Given, for example, unfavorable component tolerances, however, the operating frequency can be moved close to the resonant frequency and cause impermissibly high voltages at the components. Such a voltage rise is limited according to the invention by means of a voltage-dependent resistor. It preferably lies in series with a capacitor and takes care of a voltage-dependent shift of the resonant frequency.

Title: Laundry drier having a chamber receiving the laundry to be dried
Inventor: OBERT PETER PROF DIPL ING
IPC: D06F58/26
Filed: 1983-07-06
Abstract: In laundry driers working on the evaporation or vaporisation principle, the transmission of the thermal energy takes place indirectly via air or heat-conducting walls by contact with the laundry to be dried. The transmission entails a relatively high heat loss. In the drier according to the invention, the wet laundry is irradiated directly by high-energy electromagnetic waves. As a radiant heating source there are one or more radiant heaters (5) which are located outside or inside the drying chamber (1) and which are screened off from the laundry to be dried by walls transparent to the radiation spectrum of a radiant heater (5). The waves are deflected into the interior of the chamber by reflectors (6, 9). If the radiant heaters (5) are located outside the chamber (1), the chamber wall is made transparent to the radiation spectrum of the radiant heaters (5). <IMAGE>

Abstract: The invention relates to an alarm system for gambling machines, particularly coin-operated gambling machines, with a power section and a battery for the voltage supply (2) and with an input circuit (3) which is connected to a key switch (25, 26) and to at least one alarm switch (23, 24). The input circuit (3) is followed by a sound generator (4) and an output stage (7) with connected loudspeaker (47, 48). The power section (11, 12, 13) is connected, on the one hand, directly to the output (14) of the voltage supply (2) and, on the other hand, to a battery via a control section (18, 22). When there is voltage at the power section, the battery is continuously charged. Without voltage at the power section, the battery takes over the voltage supply. The input circuit essentially consists of two not-and components (nand gates) (29, 34). The first nand gate (29) has two inputs, one of which can be connected to earth via the alarm switch (23, 24) and otherwise has voltage applied to it. The second input (32) is connected to an output (33) of the second nand gate (34). The first input (36) of the nand gate (34) is connected to the output (35) of the first nand gate (39). The second input (38) can be connected to earth via the key switch (35, 66) and is additionally connected to the output of the voltage supply. This achieves reliable alarm signalling and operative simple possibility of acknowledgement.   <IMAGE>
